[0036] Example 1
[0037] 1. Weigh according to the following components and their weight parts:
[0038]
[0039] 2. Preparation method:
[0040] (1) Put the formula amount of MAH, DCP, and industrial white oil into the reactor for premixing, control the temperature of the reactor at 40°C, and the stirring rate at 30r / min to obtain premixed materials.
[0041] (2) Put POE, PA, PP into a small vertical medium speed mixer, stir at 70r / min for 3 minutes, add the premixed material obtained in step (1), continue stirring for 4 minutes to make it evenly dispersed. A preliminary mixture is obtained.
